How Iran’s Hypersonic Strikes in Middle East Pushes India’s Anti-Hypersonic Defence into Priority

IgMp Bulletin

The recent wave of hypersonic missile attacks launched by Iran toward Israeli territory and US-linked facilities in West Asia has become a live laboratory for military planners worldwide. What stood out was not just the political escalation, but the technical stress placed on some of the most sophisticated air defence networks on the planet. Systems that were highly effective against conventional ballistic missiles and rockets appeared far less comfortable when confronted with manoeuvring, high-speed threats travelling at several kilometres per second.

For India, these developments have sharpened the urgency around its own anti-hypersonic defence. Under Phase III of the Ballistic Missile Defence programme, the Defence Research and Development Organisation (DRDO) is developing two specialised interceptor families: AD-AH (Advanced Defence – Anti-Hypersonic) and AD-AM (Advanced Defence – Anti-Missile). These systems are not incremental upgrades; they represent a doctrinal shift toward defeating weapons that can glide, skip and manoeuvre unpredictably inside the atmosphere.

The Hypersonic Collapse: Why Traditional Air Defenses Failed in West Asia

Open-source assessments of Iran’s Fattah-1 and Kheibar Shekan variants suggest the use of manoeuvrable re-entry vehicles (MaRVs) or glide-type payloads capable of altering trajectory in the terminal phase. This is a crucial distinction. Traditional ballistic missile defence relies heavily on predicting an intercept point based on a largely fixed trajectory. Systems such as Patriot batteries or layered Israeli interceptors are optimised to calculate where a missile will be and place an interceptor at that location.

Hypersonic glide vehicles complicate this geometry. By performing lateral manoeuvres and adjusting altitude during descent, they can force constant recalculation. Even minor mid-course changes at Mach 8–10 create massive uncertainty in the final seconds before impact. Hypersonic cruise missiles add another layer of difficulty by flying lower, often beneath long-range radar coverage, reducing detection time due to the radar horizon effect.

The lesson from West Asia is not that air defence “failed,” but that the kill chain is under strain. Ground-based radar alone may not be sufficient for persistent tracking of dim, fast-moving glide vehicles. For India’s AD-AH to function effectively, early detection must happen from above as well as below. This is where the future integration of space-based sensors becomes critical. A space-based surveillance layer can detect the thermal signature of a boosting missile and continue tracking its glide phase from an overhead vantage point, feeding refined data to interceptors on the ground.

India’s Two-Pronged Shield: Anti-Hypersonic Defence: AD-AH vs. AD-AM

India’s approach separates the hypersonic threat into two distinct categories, each requiring a tailored response.

AD-AH is expected to operate at higher altitudes, targeting glide vehicles before they descend into dense atmosphere. Its core principle is kinetic interception—essentially hitting a bullet with another bullet. AD-AM, in contrast, is designed to counter hypersonic cruise missiles operating within the atmosphere, where aerodynamic drag and lower altitudes demand different guidance logic and reaction timelines [Source: News18].

Kinetic Kill Vehicles: The Science of ‘Hitting a Bullet with a Bullet’

The physics of hypersonic interception are unforgiving. At closing speeds exceeding Mach 15 when both target and interceptor velocities are combined, even a few milliseconds of miscalculation can result in a miss by several metres. That is why systems like AD-AH are expected to rely on advanced seekers and Divert and Attitude Control System (DACS) thrusters. These micro-thrusters allow the kill vehicle to make last-second lateral corrections in space or upper atmosphere, compensating for sudden manoeuvres by the target.

This focus on DACS-enabled agility directly addresses the challenge posed by MaRVs seen in Iranian deployments. If a glide vehicle swerves in its terminal phase, the interceptor must be able to adjust course almost instantaneously. Without such agility, predictive intercept models become unreliable.

Offensive Deterrence: From LR-AShM to the Scramjet-Powered ET-LDHCM

India’s hypersonic strategy is not purely defensive. Parallel programmes are advancing offensive capabilities designed to penetrate future air defence networks. The Long-Range Anti-Ship Hypersonic Missile (LR-AShM), reportedly unveiled publicly in early 2026, is described as a boost-glide weapon with a range exceeding 1,500 kilometres and peak speeds approaching Mach 10. These milestones are based on reported disclosures and projected programme goals rather than fully operational deployment.

Similarly, the Extended Trajectory Long Duration Hypersonic Cruise Missile (ET-LDHCM) is being developed around an indigenous scramjet propulsion system. In January 2026, DRDO announced a successful 12-minute ground test of a full-scale scramjet combustor—an important but intermediate milestone toward a flight-ready system. Sustained scramjet operation at extreme temperatures remains one of the hardest engineering challenges in aerospace.

The planned BrahMos-II, a hypersonic successor to the existing BrahMos series, is also expected to target speeds around Mach 8 later this decade. Together, these offensive systems strengthen deterrence by signalling that India can both defend against and deploy high-speed weapons.

The Infrastructure of Speed: Hyderabad’s Mach 12 Wind Tunnel

Behind these programmes lies critical infrastructure. DRDO’s Hypersonic Wind Tunnel facility in Hyderabad can simulate airflow conditions up to Mach 12. Such facilities allow engineers to test aerodynamic stability, material endurance and control surface behaviour under extreme thermal and pressure loads. Thermal protection systems, including advanced ceramic coatings capable of withstanding temperatures above 2,000°C, are being refined to protect both offensive and defensive platforms.

The Hypersonic Technology Demonstrator Vehicle (HSTDV) has already served as a testbed for scramjet validation and high-speed flight control, providing empirical data that feeds into both interceptor and strike systems.

As the Iranian case study demonstrates, hypersonic weapons are not theoretical constructs. They are operational realities reshaping deterrence equations. For India, the development of AD-AH and AD-AM represents more than technological ambition—it is an attempt to rebuild the kill chain for an era where missiles no longer follow predictable paths. By combining layered ground interceptors, future space-based sensors and indigenous propulsion breakthroughs, India is laying the groundwork for a credible hypersonic defence architecture tailored for the 2030s.
